WINDOW REGULATOR.

p This invention relates to window regulamrs, lator more especially ada ted for windows that do not raise their in length. In auto- I mobile closed body construction, the rear uarter window rarely ever descends more t an about half its length on account of the curvature of the body not permittingsufficient de y in the window pocket.

1 One o the features of the. construction about to be described is that the same effects a positive lock for the window when it has been thrown to its uppermost position. This lock ia over 'and above the usual clutch lock Il used in window lifts.

Another featureof the invention is the arrangement ofthe counterbalancing spring in this typeof window liftv in such a fashion that-the same does not vibratesnd result in N the lannoying noises which are usually incident to the'customary thiatrpe afdifting lever.

S another feature is the adjustability of the device in installing it, which will be fully explained hereinafter.

In the drawings: v Fig. 1 il an inside elevation of a rear uarbfwindow frame and window well, showing the window regulator arm in two I0 positions..

Fi 2 is an inside elevation of the regula- "tnr, ing a view taken 'from the right of Fig. 3.- 4 ig. 3 is a section on the line 3-3 of is Fi .2.

e regulator comprises a circular supporting plate a adapted to be engaged in a.

, counter-bored mortise b in the window board c. In fact, thisis artially counterbored in 40 thepost d. This p ate a 1s provided with a clutch housing e. The crankshaft f through the clutch vg serves to rotatethe pins 7L.

This clutch g may be 0f any Suitable construction so as to freely rotate the pinion 45 and actuate it through the crankshaft but serving to lock when -actuated through the pinion by a stress on the window. Clutches of this type are familiar and necessary to window lifts. The'one here shown, but

50 which will not be described,v is one similar to that shown in the patentto Simpson et al., No. 1,343 410.

n will be een from Fi 3 that the pins h are riveted to platea at teii' opposite ends .-so that the plates and the pins take the place and has for its object a window regu.A

l t provided with a shoulder u ada spring used with of a driving pinion and ma be broadly referred to as a driving mem r. These pinions mesh with the teeth of the segment a' on the end of the lever j. This` lever is fulcrumed at k on the hollow stud l riveted to the supporting plate a by means of the legs m. The two discs n and o are bolted to jgether by the cap screw and nut p, and serve to orm a collar to hold the lever onto the stu The enlarged portion of the stud forms n seat forthe counterbalancing spring q, one end of which is fastened to .the stud at i', the opposite end of which is rolledover the rivet s attached to the lever.

On the end of the lever is pivoted the link ted to enator isr asgage with the pin e. The re sembled onto the window frame by first attaching the link tothe. bottom rai of the window. "The window is then shoved up to the desired limit of its upward travel and the link and lever are straightened out with the shoulder n ainst the stop. A cminterbored mortise bas already been cut in the window board. With the lever and the link on a straight .line so that the distance from the center of the supporting plate to the pivoting of the link on tne bottom window rail is equal to the distance between the center of the counterbored ,mortise and this pivoting point of the link, the supporting late will fit into the counterborc nice y. However, this will vary slightly in nearly all jobs, but it may be taken care of by simply turnin the supporting plate slightly about the ulcrum of the lever. This fulcrum of the lever u n the supporting plate being eccentric, o viously the distance between the center of the supporting plate and the pievoting of the link to the window rail may progressively increased or decreased by simply turning the supporting plate about thiseccentri'c fulcrum.v When such turning has been done as to accurately fit the su portingplatc and the counterbore, it is then fastened to the counterbore by screws. The shoulder and the stop perform a. very' useful function; lThey not only serve to line the lever and the link up to' a substantially strai ht line for the purpose alreadydescribed,

ut also for another y I with the link and the lever maintained on a 'straight line in this position, and as the lever and linkare also disabled from breaking except in one direction, it will be clear that this forms a positive lock, preventing any effort applied to the Window from causing` it to descend. The window is constrained to slide in a vertical path by the window guides: hence the thrust of the window upon the link isa dead center thrust from one pivot of the linkto the other, or

else it tendsto break the link and leverin. the direction that these members cannot break. In short, it amounts to a thrust on the center line of the three ivots of a ytogle when these pivots are allI ine, or else the pivot of the knee of the toggle is sli htly over the center line and relstrained rom any further movement in that direction. This forms an effective lock which can only be broken by a force which has a -component that travels at right an-v gls to the center lin of The usual cl'utch lock may-or may not be used. Of course, itwill be necessary if it is desired to lock the window in an intermediate position.

What'I claim is: l I

1. In a window construction, the combination of a window raineaprovided with a pair of opposed vertical' window guides and a window well, a sash slidable vertically therein, a re lator plate located at substantially the sid: of the window well, a relatively lonar lever fulcrumed on the said plate, a relatively short link 'pivoted. to the the toggle.

end, of the long leverand at substantially the center of the sash, the said lever and link being on substantially a straight line position or dead center when the window is in its uppermost position, and means on said regulator plate associated with the lever at its Iulcrum end for causing the said lever to swing upon its fulcrum.

2. lnv a window construction. the. combination of a window frame provided with a pair of opposed window guides and a window Well, a sash slidable Vtherein vertically,

a regulator plate located at, Vsubstantially the side of the window well, a relatively longb lever fulcrumed on said plate and arranged to swing from a position in which its end of larger sweep is below the fulcruin to a po'- sition when such end is above the fulcrum, means for actuating said lever, and a relatively short link pivotedto the end of the long lever and the bottom of the sash at substantiallyv thecenter, the said lever and link being arranged to break on only one side of their straight line position and arranged so hat they are in `theirsubstantially straight in'e position when th'e windowis in Vits uppermost position so as to lock the window from descending.

on said'- center y porting plate,

"plate provided with a hollow 3. In a window construction, the combina'- tion of a window frame provided with a pair of opposed vertical window guides and a window well, a sash' slidable vertically therein, a regulator plate located near one" link being provided with a stop and shoulder arrangement to prevent the lever and link breaking on the upper side of their straight line position, which straight line position they assume when the window is in its uppermost position.

In a window construction, the combination of a window constrained to slide vertically, a window board, a sustaining plate which may be applied to .the window board, a lever eccentrically fiilcrumed on the supa link connecting the end of the lever withgthe' bottom of the window, and a stop and shoulder that limits the breaking of the lever and the link, the said sustaining plate being applicable to the window board'in a plurality oftangular positions on a single center which by reason of the eccentricity of the fulcruming of the lever permits the lever and-link to be moved relativel to bring the stop and shoulder together w en the window is in its uppermost position.

5. In'za windowy construction, the combination of awindow frame including a window board counterbored to form a plate-rec'eiving mortise, a ywindow constrained toslide vertically in said window frame, and a window vregulator provided with a'circular mortise and having also a lever arm in the counterbore to bring the lever and' link'- into a position where the stopand shoulder engage.

6. In window regulator,
